Author: CDC

Severe Acute Respiratory Syndrome coronavirus 2 or SARS-CoV-2, commonly known as the novel coronavirus, is the airborne virus that causes the COVID-19 infectious respiratory disease.[1] SARS-CoV-2 was previously known as n-2019-nCoV.[1][2][3][4]

COVID-19 was first identified in Wuhan, China, in December 2019, which led to the discovery of the novel coronavirus that causes COVID-19.[1] Severe Acute Respiratory Syndrome coronavirus 2 can cause COVID-19 in babies, children, and adults of any age.[5] It spread globally, resulting in the 2019-2020 coronavirus pandemic.[6][7]

Symptoms[edit | edit source]

Symptoms are usually mild and begin gradually, although around 1 in 6 people with COVID-19 need medical help.[1] Some people become infected but don't develop any symptoms and don't feel unwell.[8] These symptoms may appear 1-14 days after exposure; most commonly around five days.[8][9]
